DAVID HESS, OF LONGLEY, OHIO.

BORING POST-HOLES.

SPECIFICATION forming part of Letters Patent No. 392,918, dated November 13, 1888.

Application filed April 2, 1888. SerialNo. 269,261. (No model.)

f0 aZZ whom, it may concern:

Be it known that 1, DAVID lines, a citizen of the United States, residing at Longley, in the county of Wood and State of Ohio, have invented certain new and useful Improvements in Boring Post-Holes; and I do declare the following to beafull,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the let tors and figures of reference marked thereon, which form a part of this specification.

The special objectof the invention is to make an apparatus with which holes may be bored in the earth for posts of anykind with aminimum of labor, expense, and time.

Figure l of the drawings is a side elevation; Fig. 2, a vertical section on line a: a: of Fig. 1, and Fig. 3 a horizontal section on line 3/ y of Fig. 1.

In the drawings, A represents the frame, consisting of the standards a a and crosspieces a a.

B is a crown-wheel at bottom, and 0 another at top, the former keyed to the screw D and the latter cent-rally threaded to work on it. Between the wheels B G, and loosely surround ing the screw, is the hollow spacer E.

The parts B G D E are axially in the same On the lowering of the screw D the well-known auger F is rotated by the wheel B and fed down by the wheel 0.

G H are twovertically-arranged crankwheels, journaled in levers I J and meshing with either of the wheels B C. By raising or lowering the levers in the keepers K L the wheels G H may be made to mesh with either of the wheels B O, and then locked by the de- By this movement the wheelO islocked,while 5 the wheel B revolves to rotate the'keyed screw. The screw D, rotating in and through the wheel 0, which is now fixed by the pawls or detents M M, feeds the auger into the ground. The work is then continued until it is desired to bring up the borings which rest upon the auger, when thelevers are unlocked, raised to the top of their keepers, and again made fast, thus locking the bottom wheel,B,and unlocking the wheel 0, which is now brought into gear with the crank-wheels. The latter are now rotated in adirection the reverse of that used when boring. The auger-screw D, being keyed to the locked wheel B,eannot turn; but the nut-wheel turns so as to make a reverse movement upward in the screw, so as to lift and carry up the borings, which are removed and the boring resumed as before.

Having thus described all that is necessary to a full understanding of the invention, what I claim as new, and desire to protect by Letters Patent, is-

1. The described means for carrying down the anger as it rotates and bringing it up with out rotation, which consists ofthe spaced horizontal bevel-wheels B O, the screw 1), keyed to wheel B and working in a nut of wheel 0, the locking pawlsor detents M M, and one or more crank-wheels journaled in shifting devices, substantially as shown and described.

2. The detents M M, combined with shifting-levers I J and wheels B O G H, as and for the purpose set forth.

3. The spring-catches N 0, combined with the shifting-levers I J and wheels B O, as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID HESS.
